Comparative analysis of the proteins in the secretion of larval salivary glands in the tribe Chironomini






Zoologicheskii Zhurnal 74(5): 53-67

Comparative analysis of the proteins in the secretion of larval salivary glands in the tribe Chironomini

The electrophoretic patterns of the proteins from the secretion of salivary glands of the larvae of 19 species (5 genera) of the tribe Chironomini differing in ecology, behavior and phylogenetic relationships were compared. Some characteristics of the secretion were found to be common to all the studied species, hence they are not dependent on the ecology, behavior and taxonomic state of chironomids. These characters are: the occurence of the secretion in the salivary glands of larvae, the numerical set of the proteins in the secretion, the range of the sizes of these proteins and the quantitative predomination of giant proteins (GSP-group) in the secretion. On the contrary, MSP-I and MSP-II groups of proteins have significant intergeneric differences. The electrophoretic pattern, the size and the variability of the proteins in these two groups are specific to each of the genera of the tribe Chironomini and can be used as biochemical markers under the diagnostics of the larvae from these genera.
